Disclaimer: I am not responsible for any injuries such as bruises, scratches, or drawn-on items.

Step 1: Gather Items

Gather one "Pentel  Wow! bk440" pen and a random pen that uses a spring. 
Someone to prank.

Step 2: Dissasemble the Pens

This should come natural to you, you should be a hacker !

While doing this you should make sure that you separate the pieces so you know which goes in to the "Pentel Wow! bk440' pen case in the next step.

Step 3: Insert Spring

So, seeing that you've come this far I'll show you how to do this.  Take the spring from the random pen and drop it into the "Pentel  Wow ! bk440" pen case. 

Step 4: Assemble Pen

Assemble the pen the way you found it, by dropping in the ink cartridge and and pushing the clicky-thingy back in. 

Step 5: How to Prank Someone With the Pen

Give somebody, preferably a person that wouldn't mind a nudge of humor, the pen and ask them how to disassemble the pen. If you built it correctly the button, ink cartridge, and second spring should shoot out at them.
